Shotguns manufactured since 1986 will require their magazine tube to be modified. These will fit any 12 gauge model 870, 887, 1100, or 11-87 shotgun, then. The dimples inside magazine tubes that hold a plastic spring retainer will have to go, else the shells cannot slide properly. Manufacturer is Choate Machine Tool of Arkansas.

It will increase the magazine capacity from 4 to 7 rounds in the tube. It is designed to match Remington Shotguns with 20 inch barrels. Finish is matte blued on all surfaces. No NYC.
